I have an arm64 (aarch64) test program on MacOS that calls

So far so good.
But now I install a system.ErrorProc and run the same program. It
emits, instead of the EBusError, Runtime Error 214.
This puzzles me.
Of course, I can add a bug report.
Is this really a bug? This depends on what you do in your ErrorProc
implementation, doesn't it?
